Abstract

In an air quantity measuring device for a continuously operating fuel injection system, the baffle plate which actuates the control piston of the fuel quantity distributor by way of a lever, is provided with a raised portion on the inflow side thereof; to reduce the air-resistance of the baffle plate in a predeterminable manner, the peak of the raised portion is disposed eccentrically to the baffle plate in the lever-side half thereof, whereby the same air quantity measuring devices can be used for different measuring ranges by installing baffle plates with differently shaped raised portions.
